Then at higher loads or WOT situations the flow path of the passengers side is reversed due to the postive pressure inside the block now needs to be evacuated. With the throttle open both ports now see a vacummn signal, a weak signal, but enough to move the blowby gasses and building pressure inside the block.

Thank you Nathan, the sad thing is thats what I've been saying the whole time.

Normal PCV flow is ONLY during VACUUM condition, i.e. part throttle.
At WOT, its just as you said and the blowby gases escape out the pass side and into the air stream.

I can't believe that is so hard to understand.
